Normal to have this in error logs?

I've been seeing these Exceptions in the error logs for weeks now. It happens whenever I setup an Orchard site from scratch. I don't see any problems so I haven't bothered finding out if it's normal until now.

It's been there since v1 ;) Actually at setup we check for this table to see if the db has already been created. If it results in an exception then we can proceed, but the exception is also logged. So everything is fine here.
